UNITED STATES W LIJAM 11- L WI qr PITTSBURGH. .PE,N. AN A aamn epksmApplication filed June 29, 1925. sen-a1 naaa'wof To all whom it mayconcern:

Be it known that I OLIVER P. MEGAHAN,

a citizen of the, United States, residing at New Castle, in the countyof'Lawrence' and State of Pennsylvania, h'ave'invented a certain new anduseful Improvement in Rail- -road Ties, of'which' the following isaspect fication.

According to railroad engineers arolled I-beam makes a substantial anddurable cross tie for light work such as on street railways, but forrailroads where the traflic is heavy a beam of that form is too rigidand lacks the resiliency necessary for the 5 preservation of theintegrity of the rolling stock. I

The object of the present invention is the provision of means wherebythe I-beam can be utilized and resilience obtained adapting it for useon heavy traific roads.

The invention is embodied in the examples herein shown and described,the features of novelty being finally claimed.

In the accompanying drawing Figure 1 is a perspective view showing thefractions of rails supportal on the cross tie and chairs.

Fig. 2 is a'view in side elevation of the same looking toward the end ofthe tie and the side of a rail thereon.

Fig. 3 is an elevation looking at the side of the tie and an end of arail supported therein.

Fig. 4 is a top plan view of the chair and a buffer therein.

Fig. 5 is a view like Fig. 2 showing a modification in which the chairis made as an integral part of the tie.

Fig. 6 is also a view like Fig. 2 showing a modification in which theupper cross part of the head of the tie is rounded or bent and the baseof the chair correspondingly rounded to fit thereon.

In the views and referring more particularly to Figs. 1 to 4 thecharacter 7 desig- 1 nates the cross tie which is of rolled iron I- beamform and of the usual or suitable length to support the two rails 8.

The chair which is of yoke-form consists of an iron or steel platehaving a base or intermediate portion 9 with its ends 9 bent updivergently from each other and then outwardly as shown at 9 to formseats upon secured to thehead flanges oft-he I b whichthe'rail issupported.- The I chair; is

by means ofthreaded bol'tslO having n s 11 i thereon, spring washersbeing interposed between the nuts and the I-beain' flange: -j Therail-is secnred "toIthe twisty- 1a bolt 13 having 'spi-ke-like head"that' la-ps over the baseor the ma,- a nut 14 being provided" to: holdthe bolt fairly firmly gripped to the rail. The bolts 13 have squareshanks andthe flanges 9 are provided with square holes 15 to keep theheads of the bolts 13 from turning out of functioning-position.

Loosely seated in the chair is a curved spring 16. This spring is madeof such length that it rests on the intermediate portion 9 and fits atits terminals closely in the corners formed at the junction of the bentup portions 9 with the base or intermedi I ate portion 90f the chair.The spring 16 is made of such width. that its terminals are adjacent theheads of the bolts 10 and the spring is prevented from dislodgmentin ahorizontal direction from its position under the rail. Said springfurther is made of a depth so that normally it does not contact withthe, lower side of the rail but of such depth that when the rail isdepressed with 7 an abnormal load it serves'as a bufi'er.

The parts 9 are made resilient so that when the load passes over therail there is a yielding efl'ect akin to that obtained with awooden tie.In this action the parts 9 are slightly spread but this is permitted. byreason of the slipping spike like heads of the bolts 13. I

In Fig. 5 the spring members 9 corresponding to the spring members 9 ofFigs. 1-4 are integral with the I-beam, otherwise the construction andmode of operation are the same. I

In Fig. 6 the upper surface'of the tie and 95 the lower face of thechair are correspondingly curved so that the joint at 17 between themprevents horizontal slippage in the direction of the track. The efi'ectof this form of joint is that possible tendency of horizontal strain tocut the bolts 13 is avoided.

The base flanges of the tie are shown as provided with spurs 18 cut inthe opposite margins and bent down, such spurs afl'ording a better gripof the tie upon the road bed and preventing creeping.

The forms of the parts can be changed without departing from the gist ofthe invention as claimed.

What I claim is:

1. A chair for a railroad tie consisting of a pair of opposinglyinclined resilient members and a resilient buffer member interposedbetween said inclined members.

2. A chair for a railroad tie consisting of a pair of opposinglyinclined resilient members and a curved resilient buit erlmemberinterposed between said inclined members.

8. A chair for a railroad; tie consisting of a base portion having itsends bent to form resilient rail receiving members, means for securingsaid base portion tothe tie body, and a resilient buffer member seatedon said base and held'from dislodgment horizontally by said securingmembers.

4. A rigid railroad tie body and a chair therefor consisting of a pairof opposingly inclined resilient members and yielding means for securingthe rail thereto.

7 5. A chair for a railroad tie consisting of a plate having its endportions bent upwardly to form divergently inclined resilient membersand means whereby a rail may be secured to said end portions.

6. A chair for a railroad tie consisting of a plate having its endportions bent to form divergently inclined resilient members, meanswhereby a rail may be secured thereto and an upwardly curved resilientbuffer member placed between said inclined resilient members. 4

7. A chair for a railroad tie consisting of a plate having itsendportions bent to form divergently inclined resilient members andmeans for securing the chair to the tie body adapted to prevent slippagein relation thereto.
